EGG-BEATER.

SPECIFICATION forming part of Letters Patent No. 631,715, dated August22, 1899.

Application iiled March 2, 1899. Serial No. 707,509. (No model.)

T all whom it muy concern/.-

Beit known that LTHOMAS HOLT,of Tarrytown, in the county of Westchesterand State of New York, have invented a new and useful Improvement inEgg-Beaters,of which the following is a specication.

My invention is in the nature of a device for beating eggs, cream, ormaterial for cakes which is designed to accomplish its result morequickly and effectively and withoutleaving any unbeaten residuum in thebottom of the vessel.

It is an improvement upon that form of beater in which two rotatingbeater-bows are arranged side by side on dilerent axes eccentric to eachother and in rotating work one into the other; andit consists in thepeculiar construction and arrangement of parts, which I will now proceedto more fully describe, reference being had to the accompanyingdrawings, in which- Figure lis a side elevation; Fig. l, an enlarged endview of the handle, partly in section. Fig. 2 is an enlarged top View;Fig. 3,a section through line 3 3 of Fig. l, and Fig. 3 a sectionthrough line 3 3a. Figs. 4, 5, 6, and

- 7 are details; and Figs. S, 9, and 10 are side views showingmodifications of the rotating beaters.

In the drawings, A A are two rotating dashers or beater-bows arrangedside by side on independent axes B B, eccentric to each other, andformed by a single stout bent wire. The beaters have at their upper endstwo intermeshing gear-wheels d a, which are turned in anoppositedirection by a crown-wheel C through a crank-handle D. Thisgeneral form of beater is as so far described already in use.

I will now proceed to describe the novel features of my invention. c

The beaters A have each a circular portion a. and a shank portion a2,which in this instance are stamped out of a iiat piece of sheet metal ina single piece. The lower circular portion of the beater is stamped withan oft'- setting lug 0.3, which is perforated to receive one of theaxial bars B, and the upper ends of the Shanks are rigidly fastened tothe two small gear-wheels, which being perforated and inclosing theaxial bars form the upper bearings for the rotating beaters.

The circular portion a' ot' the beater has its two op` posite sides bentsoas to stand neither radial to the center ot' revolution nor yet atright angles to the radius, but at an angle between these twopositions,as shown in Fig. 3,in which the plane of the blade from thebottom to the top of the bow crosses the circumferential path indicatedin dotted lines, with its outer edge in advance or leading. The purposeof this is to cause the inclined blades to gather the material and throw it in to the center. The upper portion of the beater a2 is stampedto a curved form in cross-section, as seen in Fig. 3a. The object ofthis is twofold-first, to give by its hollow or corrugated form alongitudinal stiffness, and, secondly, to cause the shank portion inrotating about its axial rod to pass edgewise through the material withthe least possible resistance, and this it does by being curvedtransversely to the arc of a circle described about the axial rod.

E is the handle of the beater. This is made from a iiat bar of metalbent in the middle into an elliptical bow and having its two endsextended downwardly and connected rigidly to the axial rods B B, ashereinafter described. The elliptical loop portion of the handle isspecially constructed to give a irm grasp in the palm of the hand, andfor this purpose vthe metal of the bar is split longitudinally (seeFig. 1) and then spread apart to form two bows e e, which are thenconnected together on top bya broad flat plate e', which is stamped ofsheet metal and applied to the two bows e e by means of clips or flangese2 e3, bent around the bows and tightly pressed thereupon, so as to forma firm and rigid connection. This holds the bows to their proper spreadand gives a broad bearing for the hand for holding the beater steadilywhen turning the crank.

The lower part of the two branches of the handle and the upper ends ofthe axial rods B B are rigidly connected together, and for this purposeI form a metal block F (see Fig. 4) with a holef through it and withseats f'. In these seats the upper ends of the rods B B, which arecurved to correspond, are clamped between the block and the lower endsof the handle-bars by means of a bolt |or rivet f2. This when tightenedAup firmly clamps the handle and the axial rods to- IOO gether, so thatthey cannot become loose or detached. To further fix the block in placeagainst turning on the bolt f2, a halt-round seat f3 (or a perforation)is formed in the upper end of the block, which receives a second boltf4, that forms the aXis of the large gearwheel.

In Fig. S Ishow a modication of the beaterbows. These are madefrom astraight strip of material and have two shanks connecting with eachdrivin g-wheel. This I regard as the most simple and practical form ofmaking the bows. For connecting them to the gears the latter are formedwith square hubs rm., Figs. 5 to 8, with little indentations m. Intothese iudentations iit the inturned ends m2 of the upper ends of thebeatershanks, and a square ferrule or thimble ma, pressed upwardly overthe ends of the shanks, secures them rigidly to the gears. This sameconnection may be employed with the single shank shown in Fig. l; but Ido not confine my invention to this special form of connection, as theshauks and the gears may be connected `together in various simple andpractical ways.

In Fig. 9 is shown another modification of the beater-bows. This onlydiffers from that shown in Fig. 8 in the following particulars: In Fig.8 the angular positionof the bow from bottom to top is the same and isarrangedto gather the material and throw it inwardly. In Fig. 9 theblade of the bow is given a spiral twist, which causes the lower half ofthe bow. to gather the material and throw'it inwardly, while the upperpart bya reverse inclination throws it outwardly, or vice versa.

In Fig. l0 a further modification is shown, in whichl three blades toeach beater, instead of two, are employed.

In detnin g myinvention with greater clearness I would state that I amaware that it is not new to have two bowed beaters rotating ou separateaxial rods in close proximity to each other, the blade of one bow beingso timed as to pass in its rotation between the blades of the other bowby means of gearing substantially the same as shown by me, and I do notclaim this broadly. .Onthe other hand, I am aware that an egg-beater hasbeen provided with a blade whose plane occupies an inclined position tothe radial line, and I do not claim this broadly. My invention consists,so far as this feature is concerned, in combining these two old featuresto produce an entirely new result by coordinated action.

'Where a beater rotating about a single central axis has its bladesinclined to the radial, its rotation soon causes the entire contents ofthe vessel to start in a whirling action, which from centrifugal actionnaturally causes the liquid to trend away from the beater and keep outof its reach and which stops all beating action. On the other hand, whenthere are two bowed beaters on independent axes, or axes eccentric toeach other, but with blades that are not inclined to the radial,

and which will be found in the bottom of the vessel when the beater isremoved. With my Vinvention the two beaters preclude the continuo uswhirling and centrifugal action which a central set of inclined bladeswill produce, and at thesame time it will continually draw everyparticle of the outlying zone of material into the center, wherecomplete agitation exists, so that practically every particle of Y thematerial in the vessel will be converted into a frothy mass without anyunbeaten liquid residuum.

Having thus described my invention,.what I claim as new, and desire tosecu re by Letters Patent, is-

l. A beater consisting of two rotating bows arranged on independent axesside by side and eccentric to each -other and having the blades of thesebows set at an inclination to the radial line substantially as andV forthe purpose described.

2. A beater consisting of two rotating bows arranged on independent axesside by side and eccentric to each other and having the blades of thesebows set at an inclination to the radial line, the inclination of thelower half of the blade being reverse to that of the upper half,substantially as and for the purpose described.

3. A dasher for a beater consisting of a circular ring lwith a singleoffsetting-shank both made in one piece the ring being bent to forminclined blades and the shank portion being curved in cross-sectionvsubstantially as and for the purpose described.

4. In a beater, a handle consisting of a tlat bar having its middle partbent into an elliptical bow, split longitudinally into twin divergingsections, and having between the split and divergent sections a fiatmetal plate connecting and staying the twin bows and forming a broadhandhold substantially as and for the purpose described.

5. The combination with the two lower ends of the handle, and the twoupper ends of the beater-shafts; of a spacing-block arranged betweenthe` lower ends of the-handle and having recessed seats to receive theupper ends of the beater-shafts between the block and the lower ends ofthehandle-section, and

, one or more bolts passing through the handle-section and the block andclamping the upper ends of the beater-shafts between the samesubstantially as and for the purpose described.
